A great entry level 26 mm / 1 inch tweeter from the Discovery range - don't be put off by the low price, this tweeter punches well above its weight and is capable of excellent results.
Features include a powerful ferrite magnet and tuned rear chamber resulting in a useful low resonant frequency of just 630 Hz. The soft textile dome with its wide surround offers good dispersion and extended upper response to 30 Khz.
The Discovery series offer the legendary Scanspeak superior sound at a very reasonable cost.
They combine a wealth of technical features & innovations; the sound quality to price ratio is superb.

Been looking for a supplier of replacement drivers for some years.
Willy's HiFi had just the parts at a good price and they arrived in a couple of days.
Excellent service. Even a personal thank you hand written on the invoice.
A quick delivery and the tweeters are perfect on my mission 753 freedom speakers. Easy to fit . Highly recommend.
I’m no expert when it comes to speakers, but after some research (and a strong recommendation from ChatGPT), I went with the SB Acoustics SB65WBAC25-4 as a reference full-range speaker in this size range.
Having now tested them, I can confidently say they’re probably the best speakers I’ve ever owned. The clarity is outstanding—every detail comes through with incredible precision. The bass is surprisingly full and punchy for a speaker this size, and they handle power impressively well. For anyone looking for a high-performance compact full-range driver, these are hard to beat.
Item as described and arrived quickly - and did the job. However, I suggested that anyone replacing speaker foam makes sure they have a very large pair of sharp dressmaking scissors as it was not easy cutting to size without producing a ragged edge (which I managed to hide short of a close inspection)!
